Statistical downscaling of rainfall

WebApr 14, 2024 · To further improve downscaling performance of VDSR, we include these climate variables in our very deep statistical downscaling (VDSD). The climate variables, different from precipitation, are resolvable in climate modelling and often have more reliable forecasts (Pan et al. 2024; Baño-Medina et al. 2024; Merryfield et al. 2024). WebStatistical downscaling is a process used to transform large-scale climate model outputs into meaningful information that can be used to assess climate change impacts and adaptation options. It can be used to project future changes in climate variables such as temperature, precipitation, wind velocity, and other aspects of the climate.
